# `INJECUTE_NOT_REGISTERED`

**No service is registered under this key.**

## How to fix it

Register it (addSingleton / addTransient / addInstance) before resolving it, check the key for typos, or pass { optional: true } to get undefined instead.

## Common causes

* **A typo in the key.** The message suggests similar keys ("Did you mean …?").
* **The service is registered in a fork**, and you resolve it from the parent. Forks see their parents'
  services, not the other way around.
* **Registration order in a module** that is applied later: register the dependency first, or declare it
  in the module's `ServiceRegistry<{ … }>` type so `extend()` checks it.
* **A dependency of another service**: the message's `Resolving:` line shows which service needed it.

If the service is genuinely optional, depend on `optional('key')` or call `get('key', { optional: true })`.

## Handling it in code

```ts
import { InjecuteError } from 'injecute';

try {
  // ...
} catch (error) {
  if (error instanceof InjecuteError && error.code === 'INJECUTE_NOT_REGISTERED') {
    // error.message explains what happened; error.path is the resolution chain
  }
}
```
